Treatment of 2-formyl-1,4-dihydropyridines with primary diamines gave rise to different products depending on the molar ratio of reactants. In the case of stoichiometric amounts of substrate and reactant, only tricyclic cis-diastereoisomer was obtained in yields ranging from 53 % up to 54 %. In addition, reaction of the above carboxaldehyde with primary diamines in a molar ratio of 2/1 resulted in...
